Encyclopedia of World Biography on Alessandro Volta

The Italian physicist Alessandro Volta (1745-1827) invented the electric battery, or "voltaic pile," thus providing for the first time a sustained source of current electricity.

Alessandro Volta was born on Feb. 18, 1745, in Como. He resisted pressure from his family to enter the priesthood and developed instead an intense curiosity about natural phenomena, in particular, electricity. In 1769 he published his first paper on electricity. It contained no new discoveries but is of some interest as the most speculative of all Volta's papers, his subsequent ones being devoted almost exclusively to the presentation of specific experimental discoveries.

Early Investigations and Inventions

In 1774 Volta was appointed professor of physics at the gymnasium in Como, and that same year he made his first important contribution to the science of electricity, the invention of the electrophorus, a device which provided a source of electric potential utilizing the principle of electrostatic induction. Unlike earlier...
